Description
Technical field
The present embodiments relate to sewage treatments, environmental protection technical field, and in particular to a kind of efficient process rural area is dirty
The synthesis facultative lagoon of water.
Background technique
With the continuous propulsion that Environmental is administered, the situation of rural environmental pollution receives more and more attention.
Since the environmental consciousness of rural area people is relatively weak, also lack sanitary sewage drainage collection pipe network system and centralized processing
Facility.And resident place of abode is more dispersed, causes sanitary sewage centralized collection difficult, 90% or more sanitary sewage is not
River and lake are just directly discharged into through handling.
Currently, environmental pollution is serious caused by domestic sewage in rural areas threaten rural area water head site Water resources security, exacerbate
Freshwater resources crisis.
Compared with big and medium-sized cities, rural area is more prone to Ecological Disposal technique in terms of sewage treatment, and rural area has not
Few wasteland, depression, the useless pool, marshland and farm field irrigation drainage channel, people can make full use of these advantages, adaptation to local conditions, from
And realize recycling for sewage.Under the action of the ecosystem, sewage treatment is carried out with using synchronous, this processing method
Be it is harmless, rural area water body also achieves benign cycle, lays a good foundation for sustainable development.
Summary of the invention
For this purpose, the embodiment of the present invention provides a kind of synthesis facultative lagoon of efficient process country sewage, solved with specific aim existing
Have since rural sewage treatment rate is not high in technology, arbitrarily problem of environmental pollution caused by discharge.
Mainly by being transformed using the rural area swag that leaves unused, being formed a kind of has the comprehensive processing dirt of anaerobic and aerobic
The synthesis facultative lagoon of outlet capacity.The anaerobic zone existing aerobic zone Ye You in facultative lagoon can more effectively handle waste water in this way, and
Using landform and gravity, sewage is made to flow automatically as far as possible, reduce lift pumping station quantity, keeps project investment, maintenance and operating cost minimum
Change, plays Optimum Economic benefit.This facultative lagoon processing system has the characteristics that scalp, low expense, convenient for safeguarding, operation
Process is stablized, and not only realizes being effectively treated for sewage, has also achieved the purpose that secondary cycle utilizes.
To achieve the goals above, the embodiment of the present invention provides the following technical solutions:

Grid import 104 is arranged in the 1 windward position end of body on the pool, and sewage is filtered by grid import 104, intercepts suspended pollution
Enter comprehensive facultative lagoon after object.On the pool, side slope 101 is arranged in 1 inward flange of body, preferably sets the tilt angle of side slope 101 to
30 ° -45 °, on the one hand it can reduce side slope 101 in the case where guaranteeing that body 1 scale of construction in the pool is fixed and length is set, sewage is facilitated to relax
It is slow to enter, it is on the other hand convenient that various water plants are planted in side slope 101, it plays interception and precipitates pollutant, be microorganism
Attachment, accelerated degradation nutriment are provided.Specifically, the water such as the shallower place's plantation wilson iris of 101 headwater depth of side slope, calamus
Plant, 101 water level higher depth of side slope plant reed, contour kind of cattail, Scirpus tabernaemontani emergent aquactic plant, and in 102 bottom of the area Qian Tang
Kind planting submerged plant such as watermifoil, waterweed, eel grass etc., 102 bottom of the area Qian Tang is laid with the gravel of 30cm thickness.Sewage into
During entering pool body 1, the filtering for a variety of emergent aquactic plants planted by 101 kinds of side slope is intercepted, and can precipitate particulate form pollutant,
The nutriments such as the nitrogen phosphorus intercepted are around root system of plant by nitrification, anti-nitration reaction and microorganism to the excess of phosphorus
Accumulation achievees the effect that denitrogenate, the pollutants such as phosphorus；102 bottom submerged plant of the area Qian Tang being capable of the nutrients such as absorbed nitrogen, phosphorus
Matter；What 102 bottom of the area Qian Tang was laid with that gravel is conducive to microorganism depends on and is formed and be grown to biomembrane, with submerged plant structure
At plant-microflora, the water purification ability of facultative lagoon is effectively improved.
Effluent weir 105 is arranged in the 1 lee gauge end of body on the pool, outside by effluent weir 105 by the purified sewage of pool body 1
Discharge.In actual setting, one end of grid import 104 can be set above to one end of effluent weir 105, new sewage is logical
It crosses grid import 104 to enter in pool body 1, the water body that exclusion has already passed through purification is discharged from effluent weir 105, sharp in this way
With landform and gravity, sewage is made to flow automatically as far as possible, reduce lift pumping station quantity, this facultative lagoon processing system has scalp, low takes
With, feature convenient for safeguarding.Especially with the wind-force conduct from windward position alee position, can push sewage from grid into
Mouth 104 is flowed to effluent weir 105, saves equipment cost.
Comprehensive facultative lagoon different depth forms aerobic zone (side slope 101), aerobic area (area Qian Tang 102) and anaerobic zone (the deep pool
Area 103), realize the decomposition removal of different pollutants；As shown, narrow upper width under the area Shen Tang 103, the deep pool bank protection 106 of setting
Be limited in sludge in the area Shen Tang 103, and limit the over-mixed of water body in the pool, for anaerobic organism provide one it is continual
Protection zone, and there is heat insulation effect, have and utilizes raising winter treatment effeciency；Sewage leads to after efficiently comprehensive facultative lagoon processing
The water outlet of effluent weir 105 is crossed, water body can be used as irrigation water and be recycled.
Seeping under sewage in order to prevent influences underground water source, is also provided with anti-seepage geotextile layer, anti-seepage geotextile layer is laid on
1 inner wall of pool body.
The embodiment of the present invention has the advantages that
(1) aerobic zone, aerobic area and anaerobic zone, biological species ratio are respectively formed at comprehensive facultative lagoon water body different water depth
It is relatively abundant, be conducive to nitrification, anti-nitration reaction and different microorganisms effect, reach to nitrogen, phosphorus and various organic matter removals
Effect.
(2) oxygen transport in air to root is made pool body water using the diffusion of plant root by high kind of emergent aquactic plant
Good aerobic state is kept, the aerobic decomposition of organic matter and the completion of nitrification are conducive to；Water can be absorbed in submerged plant
The nutriments such as nitrogen, phosphorus in body, the gravel that facultative lagoon bottom is laid with are more advantageous to the apposition growth of microorganism, water plant
With microorganism collective effect, plant-microorganism system is constituted, water purification ability is improved, is more advantageous to going for water pollutant
It removes.
(3) setting of Tang Zhongtang (area Shen Tang is set in the area Qian Tang) forms ultra-deep anaerobic pond, provides one for anaerobic organism
A continual protection zone reduces surface reoxygenation and enters the oxygen amount in the area Shen Tang, keeps the existence item of anaerobe in the pool
Part is conducive to bed mud thickening, part hardly degraded organic substance can be made to be converted into easily biodegradable organics, then reach the height of organic matter
Effect removal.
